Is there currently a way to have CPU temperature limits with this kernal?

Or if not then could it be added?

I'm in Australia and it gets hot here. This is not the only part of the world it gets hot. Winter can be around freezing, and summer can be mid 40s C (120F for US people). So it would be nice if in the hot weather my phone automatically adjusted to throttle itself down when it gets hot. And that way it could be more safely over clocked. If you do something intensive, it can jump to 1.7Ghz for a couple of seconds and then even if its still intensive, slow down to only 1.2Ghz and then 1Ghz etc if the temp rises above 50 C or something until it sufficiently cools.

I bet people in Arab countries would like this feature too.

Possible? Would it require a new governor?

I have installed your CheckROM™ Revo NoteHD V3 Final and added #Force launcer to memory ro.HOME_APP_ADJ=1 to build.prop. I did a reboot and installed by Recovery AbyssNote kernel 3.0. But I'm not having bootloops

Edit: no problem with bluetooth
[Galaxy Note GT-N7000 Android Development] firestonez:
1st boot no problem but after 2nd reboot got bootloop.
[Galaxy Note GT-N7000 Android Development] albireox:
You could use SetCPU. You must define a profile that lowers the CPU Frequency if the temperature is above a certain value. Also it's recommended to use the same governor for the profile defined as the one for "normal" use.

After Flushing AbyssNote v3.0.. my sgn two touch button not working after i called some1 and cut / disconnect the call after tht both touch (menu and return) button doesnt work. i need to restart the phone..

plz help.
[Galaxy Note GT-N7000 Android Development] Chris X.:
thX albireox

or you could use:

This has many advantages over setCPU.

e.g. You can use the recommend governor by angelom (lulzactive) and nevertheless You can set the profile...

AnTuTu CPU Master Pro is slightly better than setCPU but the voltages settings should be like setCPU, because in AnTuTu CPU Master Pro the mV-steps are too small.

Dear Robert, I think that the problem is not the kernel but the rom you're using. I tried Abyss 2.8 - 3.0 with Checkrom, but I had a lot of problems with that ROM (random freeze, call drop, phone app disappearing).

Now I'm back to the best so far in my opinion, Rocket ROM v15 and no problem with abyss 3.0 (antutu 7652 @1704).

Thanks a lot as usual to Angelom; fantastic job...the only problem I think is that he has not so much residual time to update his Rhapsody ROM and he prefers to concentrate on the kernel.

This was a problem for several people (see here) but then everyone (me included) reported the problem disappeared with this very kernel.

I'm still at Abyss 2.0, for no particular reasons other than I've taken no time at all to update anything (rom is still cassie 2.2...), so it's strange that this defecrt is reappearing for you on 3.0.

I think I found the bug regarding to the new Torch widget.

I have just noticed that the new Torch widget doesn't work properly for this kernel. For Torch widget there are 3 light levels, if you use with CF-Root kernel it works for all 3 light levels. But with this kernel, it uses one light level for all 3.
[Galaxy Note GT-N7000 Android Development] Vulpix:
It's not a bug. Since Samsung has yet to release the new sources with the 3 light levels for the browser, it won't work on the torch app. Or am I wrong?

if use smartassv2 governor, the RAM/CPU score will be lower(873/1681/1337), but 2D/3D score will be higher, same as angelom; also in this mod the fog in the 3D testing will be dark red... not looks like fog.

Hi Angelom,

Any chance to include support for Tegrak Overclock Ultimate app

https://market.android.com/details?id=com.tegrak.overclock.ultimate&hl=en

In changelog, tegrak mention that Galaxy Note N7000 is supported

For Devs,

Please set this option in your kernel config.

CONFIG_KALLSYMS=y

CONFIG_KALLSYMS_ALL=y

This will be great as we can OC/UV both the CPU and GPU.

if it is not possible as tegrak only support stock kernel for now can you create a kernel that lock the GPU to 267mhz or higher.

Mali tend to drop to 160mhz and it make some of the app that use 3d to drop fps like benchmark test or games.

here is the link on the exlplanation regarding mali gpu by tegrak.

Robert, I had the same problem with various kla1 roms, not only v17 rocket (without uv). Furthermore after the freeze at 14% during the antutu cpu test I'm not able to use the telephone at all and I need a full wipe. Have you solved with 2.5? Just to be clear, same problem with new FM 2.0. Have you tried CF kla1?

EDIT: no problem if I use 1400mhz and ondemand, problems with 1700 and lulzactive/ performance, same with antutu cpu master pro or setcpu, need to nandroid restore
[Galaxy Note GT-N7000 Android Development] robertberma:
Yes with 2.5 no problems. Now using fm 2.0 and this one is super fast and stable. Can run antutu with no problems. 7800 score. I think that this kernel runs not so good with XXLA1. But FM fot me works super.

Kernel wakelocks

Hello!

I have a problem with your kernel.

I'm using Rocket ROM v17 which, as you know, has got your v3.0. After flashing it, I rebooted twice and froze Wifi Sharing (as instructed in the OP), rebooted again and installed CPU Spy and BetterBatteryStats (and nothing else!), and my battery drains like hell because of 3 Kernel wakelocks:

wlan_rx_wake

wlan_wake

svnet

They're all related to WiFi - and in fact, when I turn off WiFi, the drain stops, only to restart as soon as I turn it back on.

This happens consistently with both Abyss and FM kernels, but never with CF, and it happens on all the WiFi networks I've tried.

Do you have any idea/suggestion about what may be causing the problem? Is there anything else I can help you with to diagnose it?

Thank you!
